源代码网推荐 1--Err Msg: "Export Failed" in .NET WinForm Viewer on Windows 98 and ME 源代码网推荐 http://support.businessobjects.com/library/kbase/articles/c2012350.asp 源代码网推荐 This issue occurs because the initialization function of the WinForm Viewer does not accept Windows 98 and ME. 源代码网推荐 This is a known issue with Crystal Reports (CR) version 9.0 and has been tracked. The Track/Problem ID is: ADAPT00123645. 源代码网推荐 源代码网推荐 2--Err Msg: "Invalid export.dll" when exporting from a .NET application（非常常见，还有报.tmp错误） 源代码网推荐 http://support.businessobjects.com/library/kbase/articles/c2013247.asp 源代码网推荐 This error occurs because the computer could not find Msvcp60.dll. The computer contains version 1.1 of the .NET framework (this version of the .NET framework does not install Msvcp60.dll to the system32 folder). 源代码网推荐 To resolve this issue and export the report successfully, move Msvcp60.dll to the application directory. 源代码网推荐 3--Err Msg: "Missing parameter value" when printing or exporting in VS .NET(丢失参数) 源代码网推荐 http://support.businessobjects.com/library/kbase/articles/c2012633.asp 源代码网推荐 This error message appears because the parameter values are only being passed to the CrystalReportViewer control, and not to the ReportDocument object (engine). 源代码网推荐 The ReportDocument object (engine) is responsible for passing parameter values when printing and exporting. 源代码网推荐 To successfully set the parameter values when you preview, print and export the report, you must pass the parameter values to the ReportDocument object (engine). 源代码网推荐 源代码网推荐 4--SetDatabaseLogon method does not propogate logon to subreports(子报表不能享受父报表的登录信息) 源代码网推荐 This is a known issue with Crystal Reports (CR) for Visual Studio (VS) .NET and Crystal Reports (CR) version 9.0 and has been tracked. The Track/Problem ID is: ADAPT00131766. 源代码网推荐 Hot Fix updates addressing this issue are available as indicated below. With the updates, the logon is now explicitly propagated to all subreports, even if the subreport tables do not share connections with the main report tables. 源代码网推荐 源代码网推荐 WebForm部分 源代码网推荐 1--Cannot print or export a report from Web Forms Viewer in Visual Studio .NET（不能导出报表） 源代码网推荐 http://support.businessobjects.com/library/kbase/articles/c2011964.asp 源代码网推荐 源代码网推荐 This is a known issue and has been tracked. The Track ID is ADAPT00118286. 源代码网推荐 You cannot access the export or print page if the current web form (containing the Web Forms Viewer) was opened as a result of redirect from another web page using parameters on the URL string. 源代码网推荐 For example, a URL with parameters looks like: 源代码网推荐 HTTP://servername/myform.aspx?myparam=123 源代码网推荐 If the URL with parameters is concatenated onto the URL to perform the print or export function, the resulting URL containing two question marks becomes invalid. 源代码网推荐 For example, the following URL contains two question marks 源代码网推荐 HTTP://servername/myform.aspx?myparam=123?_EVENTTARGET=CrystalReportViewer:_ctl1:_ctl0:_ctl1&__EVENTARGUMENT=Form1 源代码网推荐 To resolve this issue, do not use parameters on the URL string used to open the current web form. 源代码网推荐 Instead, use the Post method to pass parameters to another form. This will not result in the parameters showing on the URL. Then use Request.Form("myparam") to retrieve the parameters passed from the initial web page. 源代码网推荐 源代码网推荐 源代码网推荐 2--Exporting through the .NET web viewer only generates the first page(只导出第一页) 源代码网推荐 http://support.businessobjects.com/library/kbase/articles/c2013264.asp 源代码网推荐 源代码网推荐 This is a known issue with Crystal Reports (CR) 9 and has been tracked. The Track/Problem ID is: ADAPT00161234. 源代码网推荐 Hot Fix updates addressing this issue are available as indicated below. With the updates, the entire report is now exported 源代码网推荐 . 3--网页上有其他Web控件的时候不能导出 源代码网推荐 源代码网推荐 4--Err Msg: "Load Report Failed" when exporting to PDF from an ASP.NET application 源代码网推荐 http://support.businessobjects.com/library/kbase/articles/c2014432.asp 源代码网推荐 源代码网推荐 To resolve this error message, give the Internet Information Services Worker Process Group (IIS_WPG) account full control of the following folders: 源代码网推荐 • C:Winnt emp 源代码网推荐 • Export destination folder 源代码网推荐 To give the IIS_WPG account full control of a folder: 源代码网推荐 1. Right-click the folder and select "Properties". 源代码网推荐 2. Go to the "Security" tab and click the "Add" button. 源代码网推荐 3. Click the "Locations" button and select the computer name. Click "OK". 源代码网推荐 4. Type "IIS_WPG" under the "Enter the object names to select" box. 源代码网推荐 5. Click "Check Names". <Your machine name>IIS_WPG appears. Click "OK". 源代码网推荐 6. Check "Full Control" from "Permissions for IIS_WPG". Click "OK". 源代码网推荐 源代码网推荐 源代码网推荐 5--Parameter values are ignored when printing or exporting from Web Forms Viewer(参数在导出时候被忽略了) 源代码网推荐 http://support.businessobjects.com/library/kbase/articles/c2011912.asp 源代码网推荐 源代码网推荐 This is a known issue with Crystal Reports (CR) Developer and Advanced Editions version 9 and has been tracked.
